Resynthesize sine data from an ATS analysis file

           b - buffer containing ATS data
   nPartials - number of partials to synthesize
partialStart - partial in the analysis to start the 
               synthesis on (zero indexed)
 partialSkip - increment indicating partials to synthesize
         ptr - index into data set (0, 1)
       sineP - scaler on sinusoidal portion of the resynthesis
      noiseP - scaler on noise portion of the resynthesis
     freqMul - multiplier on the sinusoidal frequency information.
     freqAdd - value to add to frequency information.
      nBands - number of critical bands (noise) to synthesize.  
               There are 25 critical bands.
   bandStart - critical band to start resynthesis on. 
               0 is the first band.
    bandSkip - increment indicating bands to synthesize.
